Ultimate moment capacity of ferrocement reinforced with weldmesh
AbstractAn improved qualitative mechanical model which is thought to reflect more realistically the behaviour of ferrocement in flexure is presented. In light of this model, three types of existing typical quantitative models of ultimate moment capacity based on yield strength of wire, nonlinear stress-strain function for cold-worked wire and ultimate wire strength have been evaluated. For singly weldmesh reinforced ferrocement the model based on ultimate wire strength is found to be simpler, more reliable and more economical than the other two types of models. For uniformly reinforced ferrocement a new model based on yield strength proposed by the authors appears to be more reliable and economical, and simpler than other models based on yield wire strength. A simpler and more economical model based on ultimate wire strength for uniformly weldmesh reinforced ferrocement is also put forward by the authors. This model shows a closer agreement with test results than the existing models based on yield wire strength or nonlinear stress-strain function for cold-worked wire.
